Improvement in tinners  swages



UNITED ran iMPROVEMENT IN TINNERS SWAGES.

Specification forming part of Letters Patent No. 115,675, dated June 6,1871.

I, BENJAMIN Gonnrreron, of La Fayette, in the county of Tippecanoe andState of Indiana, have invented an Improved Swage for Driving the Jointsof Sheet Metal used in tinroofing and other similar purposes, of whichthe following is a specification:

Nature and Objects of the Invention.

My invention relates to the combination of a wooden block, face-plate,adjustable fluted guide, spring, and gagescrew in such manner that theseams by which sheet metal for roofing purposes is united maybe securelydriven down without breakiu g the metal at theturnin g point of thesame, thus permitting the use of an in ferior article of sheet metal andat the same time producing a close and durable joint.

Description of the Accompanying Drawing.

Figure 1 is a front elevation of the device embodying my invention. Fig.2 is a side elevation of the same. Fig. 3 is a fragmentary view of thedevice, showing the manner of applying it to the seams, and also thekind of joint or seam produced by its use.

General Description.

A is a block, of wood or metal, which forms the body of the device. B isthe handle, (represented as removed in Fig. 1,) securely attached to thebody by screws or otherwise. 1) is the adjustable grooved guide, bywhich the swage is held and guided in proper position in relation to thejoint or seam. G is the p spring by which the guide D is held in properposition. E is the face-plate, slightly beveled on the side next theguide D; and F is the gage-screw, by which the faceplate is broughtsquarely upon the seam. c

In order to the proper use of this device the edges of the sheets of tinor other metal are turned down and locked together, as shown at 1, Fig.3. The swage is then placed upon the joint, and the edges closely driventogether by, striking with hammer or mallet on the head of the body A;The slots h 7L in D, in conjunction with the spring 0, make the guide Dadjustable, and the groove on the lower and inner edge of D prevents theguide from slipping over the edge of the seam. The face-plate E, beingbeveled on the inner edge, leaves a narrow space on the edge of theseam, which is not rigidly forced down, thus forming a bead on that edgeof the same, as shown at 3, Fig. 3, avoiding the breaking of the sheetat that point.

Claim.

I claim as my invention- The combination of the block or body A, thehandle B, the adjustable grooved guide D, face-plate E, andgage-screw'F, substantially as and for the purposes hercinbefore setforth.
